Young Miles suffers from leukemia, and his greatest wish is to be Batman for the day.

Make-A-Wish Foundation, in coordination with the city of San Francisco, is helping that wish become a reality through a variety of events planned throughout the city today.

Miles’ superhero adventure begins on Nob Hill, where he’ll rescue a damsel-in-distress from the Hyde Street cable car tracks! Next up, he’ll capture the Riddler in the act of robbing a downtown vault.

Following lunch at Burger Bar, #Batkid will be warned by a volunteer flashmob that the Penguin has kidnapped Lou Seal, as they speed away from Union Square.

Once Miles apprehends the Penguin, he’ll make a final stop at City Hall, where Mayor Ed Lee, Chief of Police Greg Suhr and a huge crowd will congratulate his daring feats of justice and present the youngster with a key to the city.

“For our chapter here in the greater bay area, we haven’t had a wish of this magnitude,” says Lynne Durie, operations director for Make-A-Wish Greater Bay Area. “We really knew that San Francisco would open its heart and it would be a great experience, but we never expected the volume.”

Durie says social media played a huge role in the event’s growth, even before an official media release.

“It got picked up in social media before we even release and it just took on a life of its own,” she says.

In addition to the event tomorrow, other Batman-themed tributes are in the works, including a comic book from DC Comics detailing his exploits and own musical theme created by Hans Zimmer, composer for the Dark Knight Trilogy.

This story is absolutely incredible and so heartwarming. The fact that all of San Francisco came together to give this small boy his wish is touching and it shows the true character of those who live there. It’s sad to see such a young child have to suffer through so much pain. I’m glad that he got to enjoy the best day of his life.
